Having two recent successful WDW trips in the past year with my kids, I feel as though I have a good idea on how to plan our days... but, what IF? What if things get messed up and we end up facing long lines? We really haven't had to stand in long lines... maybe once or twice we hit the 20-30 minute mark, but that's it. Do you bite the bullet and stand in the line or do you just walk away? Has anyone ever walked away from a ride that you really wanted to do b/c the lines were just too long?
